ABSTRACT:
An apparatus for controllably mixing separately packaged beneficial agents and parenteral fluids to form an infusible mixture and for expelling the mixture at a precisely controlled rate from a delivery subsystem which includes its own self-contained energy source and is of a compact, low profile, laminate construction. The energy source of the delivery subsystem is made up of one or more elastomeric thin film, distendable membranes each having a uniform modulus of elasticity. The membranes cooperate with a base to define a fluid chamber having a fluid outlet in communication with a dispensing port for dispensing fluid from the device. The mixing subsystem includes cooperating sterile containers, one containing a parenteral fluid, such as a diluent, and the other containing a beneficial agent such as a drug.
